Atomthreads is a highly portable RTOS and scheduler for real time embedded systems. Made up of a few small C files, it can easily be dropped into any embedded system project that needs threading support. Ports to new CPU architectures require a single assembler file.

scst_qla_isp is an SCST target driver for QLogic
HBAs with the ISP chipset (22xx, 23xx, and 24xx
HBAs). SCST is a mid-level SCSI target subsystem
for Linux, which allows a remote host to access
local storage devices through the SCSI protocol.

iSCSI-SCST is an iSCSI (Internet SCSI) target
implementation on top of SCST, a mid-level SCSI
target subsystem for the Linux kernel. This
software makes it possible for remote systems to
access local storage over any TCP/IP network.

SRPT is a SCSI RDMA Protocol (SRP) target
implementation on top of SCST, a mid-level SCSI
target subsystem for the Linux kernel. This
software makes it possible for remote systems to
access local storage over an InfiniBand network.
This storage protocol target implementation offers
a higher bandwidth and a lower latency than any
other storage protocol target implementation
available for Linux.

SCST is a mid-level SCSI target subsystem for
Linux. This subsystem allows a remote host to
access local storage devices through the SCSI
protocol. SCST supports multiple network storage
protocols, including iSCSI, SRP, and FCoE, and also supports Qlogic 22xx/23xx SCSI HBAs. Strong points of SCST are its stability, maturity, high
performance, and low latency. See also the iSCSI-SCST, SRPT and scstqla2x00t projects, as well as open-fcoe.org.
